This year’s Australian Open, which begins on Sunday, was always going to be a big one for it affords Novak Djokovic the chance to surpass Roger Federer and Rafael Nadal in the race for major titles. Now of course the tournament’s importance transcends sports. Anti-vaxxers, a group that includes over half the population of Serbia, will invariably view a Djokovic victory as a victory for themselves. In Melbourne it will be not just the field against Djokovic but science versus superstition, hearsay, and ignorance.
